The combination in a soft-metal-valve device of a caslng of'sot metal, havinlg necks 3 and 4, atubel extending above an below "said necks, a curved sectionl 5, and a connection consisting of a tube 2, extending' from the section 5 into the lower end of the tube 1 ve-seat, a valve adaptperating devices therefor, and reinforcing-rings around the neck 4 and around the upper and lower ends of and formed into a val ed to said seat and o tube 1, and bolts connecting the rings around the tube 1.

4; Thecombination with the soft-metal casing, of a soft-metal ca box, and

metal cap C having a stu Iyfoke G adapted to support t aving a base-'piece recessed to receive and reinforce the stufling-box, substantially as set forth.
